13W3 to 15-Pin mini-D - Detachable Monitor Cable Connectors
(Cable - FRU P/N 96G2156 e.g. used for P70-6544)
I got the 13W3 pinout from the port of my Image-I. It IS correct.

Missing Pins
The key position pin-9, above, corresponds
with an obstruction on many system unit video ports, this
is intended to reduce the likelihood of something other than a monitor
being plugged into the port and so offers limited protection to the electronics
on the video adapter card.
DDC uses this pin for power and reassigns the ID bits
for DDC signalling.
Older monitors do not use all the pin positions available.
The following were manufactured with pins intentionally
missing:

it is always fully pinned.

From a cable that Dick Evans gave me, along with a 6091-019, here it
is-
All shields are tied together to shield on HDD15 and pins 4,6,7,8,10,11
Pins 5, 12 and 15 are NC

Waiting for SOMEONE to send me the pinout of a WORKING Image-I
to 5BNC cable, used on a 6091-xxx monitor.
